Anastasia's Mate: Knight and Rook on the Edge of the Board
Anastasia's mate is a checkmate in which a knight cuts off the king's escape squares while a rook or queen delivers mate along the edge file, with the king hemmed in by one of its own pawns.
The mating picture
In the standard picture the black king sits on h7 with a pawn on g7. A white knight on e7 covers g8 and g6, the two squares on the g-file that the pawn does not block. A white rook or queen then checks along the h-file, covering h8 and h6 at the same time. Every flight square is gone: g8 and g6 to the knight, g7 to the king's own pawn, h6 and h8 to the heavy piece.
The pattern is named after the 1803 novel "Anastasia und das Schachspiel" by Wilhelm Heinse, in which it appears.
The typical lead-in
The knight usually arrives on e7 with check against a king on g8, forcing it toward the corner. Then the h-file has to be opened and occupied. If the file is already open, a rook or queen simply swings over. If a pawn or piece stands on h7, the attacker often sacrifices the queen there: Qxh7+ Kxh7, and a rook lands on the h-file with mate.
Note the order: the knight check comes first because it takes away g8 and g6 before the king can use them. Once the knight is on e7, a king on h7 or h8 is lost to any heavy-piece check on the h-file that cannot be blocked.
What to look for
The ingredients are an open or openable h-file, a knight that can reach e7 (or e2 against a white king), and a defending pawn still on g7. The pawn is critical: if it has moved, the king may escape through that square. Players miss this pattern because the knight on e7 seems to be doing little, but it is quietly covering two of the most important squares near the king.
Knight-and-rook patterns like this one show up again and again in real games, and the ones you miss in your own games are the best ones to drill.
How to spot it
- Look for an enemy king on the h-file or near it, with its g-pawn unmoved.
- Check whether your knight can reach e7 or e2, ideally with check.
- Make sure the h-file is open, or can be opened with a sacrifice on h7 or h2.
- Confirm that nothing can block between your rook or queen and the king.

35.Ne7+ Kh7 36.Qh3#
Ne7+ checks the king on g8 and from e7 the knight covers g8 and g6. The king must go to h7 or h8, and either way Qh3 is mate: the queen travels from d7 down the c8-h3 diagonal and checks along the open h-file. The pawn on g7 blocks the last escape square, and Black has no piece that can block on h4, h5 or h6.
